MOLDING"- MACHINE.

srncrrrcn'rron forming part of Letters Patent No. 735,347, dated August4, 1 903.

Application filed April 24,1903.

To all whom it may concern:

Be it known that I, JOHN W. DEARSLEY, a citizen of the United States,and a resident of Racine, in the county of Racine and State ofWisconsin, have invented certain new and useful Improvements inMolding-Machines; and I do hereby declare that the following is a full,clear, and exact description thereof.

The invention consists in certain peculiarities of construction andcombination of parts hereinafter particularly set forth with refer enceto the accompanying drawings and subsequently claimed, the object of theinvention being to provide simple economical machines bywhich tofacilitate the setting up of molds in foundries, a vertically-adjustablepattern-support being embodied in each machine.

Figure 1 of the drawings represents a side elevation of amolding-machine in accordance with my invention, partly broken away andin section; Fig. 2, a vertical section view of the same machineorganized for setting up molds in ends of three-part flasks; Fig. 3, aplan view of the machine as shown inthe second figure; Fig. 4., anothervertical section view of the machine organized for setting up molds inthe main or body portions of said flasks; Fig. 5,a partly broken planview of the machine as organized in the fourth figure; Fig. 6, avertical section view of a mold in a three-part flask,and Fig. .7 ahorizontal section view indicated by lines 7 7 in the first figure. l A

Referring by letter to the drawings, A indicates a hollow column thatconstitutes the standard of my improved molding-machine,

' this column being expanded at its lower end in order that itmay standupright. The upper end of the column is horizontally flanged to form atable B, upon which to se cure a stripping-plateO or other device.

Arranged in the column A is a spider D, having the arms thereof providedwith detachable flanged wea plates E,held in place by screws, and tocompensate, for wear filling-strips are inserted from time to timebetween said plates and the spider-arms.

The hub of the spider D is provided with a lower socket for theengagement of a screw threadedshank b, pertaining to a shackle F,

Serial No. 154,076. (No model.)

that has pivotal connection with one end of circular springs I areengaged by pins (1, that also engage openings provided in the leverarm Gand link H, the latter being preferably provided with aseries ofpin-openings in order to provide for varying the tension of saidsprings.

The hollow column A is provided with an exterior guide 6 for avertica1ly-adjustable bolt f, and held on the bolt tight against theguide by means of a nut g is a stop J in the downward path of the leverG, that is herein shown as having an over and under rounded centralportion provided with a transverse slot that tapers from both endstoward the middle, as shown in Fig. 1, this slot being loosely engagedby a screw-threaded pin K, on which nuts 71 are run against lever-facingwashers i, said pin being adj ustably held in the lever-slot by means ofsaid nuts. Made fast in the upper end of pin K is a springlatch L, andwhen the lever G and parts therewith are lifted the latch engages with acatch j, that depends from the table B aforesaid. Held by set-nuts 7c inadjustable connection with the latch L is a screw-eye m, and thisscrew-eye is connected by a link n with a handle M, that is shackled tothe afore said lever. By means of the adjustable pin K and latchmechanism above specified predetermined upward throw of lever G andparts therewith against resistance'of springs I may be accurately gaged.

The 1 1 c th spider D qri ed wit an upper socket for the engagement of ascrew-threaded shank or stem ofa pattern, and, as herein shown, it isengaged by the shank p of a pattern N, that is, guided vertically in thestripper-plate C aforesaid.

The patterns herein shown arejfor setting up molds for straw-cutter feedrollersof variable length in three-part flasks, the pattern N being theone on which the molds in the main or body parts of said flasks aremade. The pattern P (shown in Figs. 2 and 3) is the one on which themolds for flanges of the feedrollers are set up in the end parts of thethreepart flasks, and in Fig. 3 is shown a patternpiece Q for formingthe runner in the mold.

To set up molds from the patterns herein shown the pattern P andpattern-piece Q are first assembled on the stripping-plate G, thepattern N having been lowered in the column A to leave its upper journalend extending through a corresponding center opening in the formerpattern. When a sufficient number of molds have been made in ends ofthreepart flasks, the pattern-piece Q is removed and molds made in otherends of such flasks, after which the pattern P is removed and thepattern N lifted by an operation of the lever G to a predeterminedelevation above the stripper-plate 0, according to the length it isintended to have the feed-rollers. The molds in bodies of three-partflasks are now made on the exposed part of pattern N, this pattern beinglowered at the completion of the ramming up of each mold to permitremoval of said mold and flask part containing same, after which theseveral parts of each flask, with the molds therein, are assembled forpouring.

It will be understood from the foregoing that the lift and fall of thepattern in connection with the lever-controlled spider D is accuratelydetermined by the set of stop J and the pin K, the range of movementdepending on the length of pattern or pattern-stem and the playnecessary to clear the mold formed on said pattern.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A molding-machine comprising a hollowcolumn standard, apattern-supporting device having the form of a spider arranged in thestandard, detachable wear-plates in connection with arms of the spider,and means for raising and lowering said spider.

2. A molding-machine comprising a vertically-slotted hollow-columnstandard, a pattern-supporting device arranged in the standard, a leverhaving an arm extending through the standard-slot and connected to saidpat-' tern-supporting device, a link connecting the lever and column,and a circular spring con nected at its ends to said lever and link.

3. A molding-machine comprising a vertically-slotted hollow-columnstandard, a pattern-supportin g device arranged in the standard, a leverhaving an arm extending through the standard-slot and connected to saidpattern-supporting device, a link connecting the lever and column, astop vertically adjustable in the downward path of the lever, a latchadj ustably connected to said lever, and alatchkeeper depending from anupper table-flange of said column.

4. A molding-machine comprising a vertically-slotted hollow-columnstandard, a pattern-supporting device arranged in the standard, a leverhaving an arm extending through the standard-slot and connected to thepattern-supporting device, a link connecting the lever and column, astop vertically adjustable in the downward path of the lever, ascrewthreaded pin engaging a lever-slot that tapers from both endstoward the center, lever-opposing washers and set-nuts on the pin, aspring-latch connected to the upper end of said pin, and a latch-keeperdepending from an upper table-flange of said column.

5. A molding-machine comprising a vertically-slotted hollow-columnstandard,a spider arranged in the column and provided with upper andlower hub-sockets, a shackle having a shank in screw-thread connectionwith the lower hub-socket of the spider, the upper hub-socket of saidspider being for the engagement of a screw-threaded pattern shank orstem, a lever having an arm extending through the column-slot andconnected to the shackle, a link connecting the lever and column, andmeans for regulating the degree of lever-controlled ascent and descentof the aforesaid spider.

In testimony that I claim the foregoing I have hereunto set my hand, atRacine, in the county of Racine and State of Wisconsin, in the presenceof two witnesses.
